Which cost refers to the additional cost incurred by

[4(2/3) + 5(1/6)] × 45% of 240 = ?

(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 ^(1/3) = 8²

5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630

672 ÷ 28 × 24 + 363 – 309 =?

555.05 + 55.50 + 5.55 + 5 +0.55 = ?       

(23 × 8) – (13 × 5) + 67 =? x 6          

375% of 320 - 80% of 40 ÷ √256 = ?

36.76 + 2894.713 + 34965.11 =?

(〖(0.4)〗^(1/3)  × 〖(1/64)〗^(1/4)  × 〖16〗^(1/6)  × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3)  × 4^(-1/2)  ×〖1024〗^(-1/4) ) = ?

276 ÷ 11.5 + 12 = ? x 3
